⚡ Nanoseconds to Julian Years: the quick answer

1 ns = 3.16881 × 10⁻¹⁷ a 1 nanosecond equals 3.16881 × 10⁻¹⁷ Julian years

To convert nanoseconds to Julian years, multiply the value by 3.16881 × 10⁻¹⁷. To go the other way, multiply Julian years by 3.15576 × 10¹⁶ to get nanoseconds.

↔ Convert Julian years to nanoseconds instead

🧮 Formula

Nanoseconds to Julian Years
a = ns × 3.16881 × 10⁻¹⁷
Julian Years to Nanoseconds
ns = a × 3.15576 × 10¹⁶

Where

  • ns = the time in nanoseconds
  • a = the time in Julian years
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per nanosecond) ÷ (seconds per Julian year).
